Add labels from label-schema.org to the generators

[jstrachan]

microbadger looks cool
https://microbadger.com/

and has a set of canonical docker labels we should automatically add into our docker images as part of a build

[jstrachan]

doh raised it here too:
fabric8io/docker-maven-plugin#492

but at the fabric8 layer we know a bit more about the image already I guess and can reuse metadata from the kubernetes annotations etc

[jstrachan]

e.g. we already have lots of the git URL / tags / jenkins build stuff as annotations in the yaml

We should add the "standard" labels fromhttp://label-schema.org/rc1/ and add it via the generator for all the information we find.

@rhuss what all labels fall under the 'standard' category here http://label-schema.org/rc1/ ?

Which don't start with docker.* or rkt.* ?

Apparently, S2I doesn't allow to override images labels.
s2i build . centos/ruby-22-centos7 hello-world-app

Though, s2i images do have schema labels of their own, these are the labels in the fabric8/s2i-java image.

So, I think I'll only append the schema labels for Kubernetes mode.
